One of Blackstone Group’s senior dealmakers in New York is relocating to London to lead the global alternative asset manager’s energy investments in Europe, the Middle East and Africa, as the firm attempts to raise its second energy fund.

Mustafa Siddiqui, a managing director at Blackstone Energy Partners, will take on a newly created role as head of BEP’s energy activity in Europe, the Middle East and Africa, according to two people familiar with the situation.

Siddiqui will report to David Foley, BEP’s chief executive based in New York, one person said. Siddiqui joined Blackstone in 2009 and has been involved in several Blackstone energy investments, including Royal Resources and Alta Energy.

The move comes as BEP attempts to raise its second energy-focused fund. At an investor day earlier this month, Blackstone’s global head of private equity Joseph Baratta said the fund was “substantially larger than” a $2.5 billion predecessor.

BEP has invested over $6.6 billion of equity in 18 deals in sectors such as oil and gas, renewables, natural resources and power generation, using Blackstone’s energy fund and global private equity fund.

In May BEP set up Global Water Development Partners, a venture that aims to invest hundreds of millions of dollars to build facilities that will convert salt water into fresh water and treat wastewater in Africa, Asia and Latin America. Blackstone is also in talks with headhunters to find investment professionals to target power developments in Africa and other emerging markets.
